11 people injured in subway explosion: officials

Eleven people were injured Monday after an insulator exploded on a subway train in Gunpo, just south of Seoul, officials said.

The explosion occurred around 6:56 p.m. as the train was entering Geumjeong station on Line 4, causing some of the train's

windows to break and wounding eleven people on the platform, police and fire officials said.

The wounded were taken to a hospital, they added.

"It appears that the accident occurred as an insulator connecting the train to the electric supply equipment suddenly exploded," an official of the train's operator KORAIL said, adding that the exact cause has yet to be determined.

The train was moved to a garage after all passengers were let off at Geumjeong, officials said.

Subway services on the same route were resumed around 7:04 p.m.(Yonhap)
